To all whom it may concem:

Be it known that I, WILLIAM R; G RNER, a citizen ofthe United States,and a resident ofErie', in the county of Er-ie' and State ofPennsylvania, have invented certain .new

Infcarryirfgflut my invention, 1 provide a 11131111 body portion'lhaving araikflahge 2. The body. portion isirecessed on" one: sidethereof as shown at 3 Fig. 2. A central hub port on .4 is providedfthishub :bIeing horedto receive'ithe axle 5.

An auxiliarydisk 6.-is provided whieh fits 1n the recess Qfhis disk aswillibe observed from Fig. 2 is'beveled .fltom Ashe center oi' twardlysoas tof pr,ovide a hearing on theflhllb .4. In Fig. 1 it ivilllbeseenthat I have provided Jugs 7 and?" which are inform applicable toan internal combustion jtegrai with the .wheel 1' and whiqh .projeet :3but 'itvzhas a'vervslight' jplay in {one direction.

will be observed from Fig. 1 there is an elliptical shaped opening 10*inthe disk arranged to receive the hub 43 T5118 major axis of the opening10 ,is in alinemejnt with the openi'ngsB and with'the center of the lugs7'a11d 7.

' In the drawings 1 have shown ,the disk 6 spaced slightly. from" theupper inner e geofthe ibodjv vportion 1,.bnt .this is iorthe'pnr oseofsilliistration' only, since as amattero factfthe movementof theauxila'ry disk 6 is very slight, say a few ,thousandths of an inch"."It-will 1B6 observed that thereis no movement oithe ailxili'aryidisk atright angles; thatvis, along the mino'r aiiis of the "elliptical shapedopening;

"The'pi-t rnan 11" is OOIll'flGbtBd to ,the aux-V il iarydisk-byine'ans' of'a pin =12at a lpoirit in 657" on the body portion 1.

alinement with the major axis of the elliptical shaped opening 10, theconnecting rod 12 also being secured to the pin.

The auxiliary disk 6 is provided with cutaway portions 13 so as tocounter-balance the weight of the connecting rod, pitman and pin, inother words, to render the wheel as a whole with its connections,counter-balanced.

From the foregoing description of the various parts of the device, theoperation will be readily understood. Assume that the wheel is turningin the direction indicated by the arrow in Fig. 1, the thrust of the pitman is in the direction of movement of the wheel in the position shownin Fig. 1. The disk 6 having settled very slightly is in close contactwith the lug 7, and therefore the force communicated by the pitman 11 istransmitted to the body portion 1, the axle 5 acting as a fulcrum. Theresistance at the rail causes the pitman to act as a lever to propel thewheel as a whole forwardly.

Consider the conditions now when the wheel has turned 180. In thisposition the pitman is moving rearwardly and owing to the lever actionthe force is applied now at the top of the wheel on the opposite side ofthe axle. A wheel constructed according to this invention tends toequalize the pressure so that the motion of the wheel is more uniformthan in the ordinary construction.

In Fig. 3, I have shown a modified form of the device in which the bodyportion 1 is recessed at 3 on a taper or bevel, this recess being deeperat the outside and gradually decreasing in depth to the hub 4;. Theauxiliary plate 6' is of a uniform width so as to give a central beamingfor the plate. It will also [be observed that the recess 3 is on theinside of the wheel. In this fornr of the device, the connecting pin 12passes through an opening 12 in the main body portion and is secured tothe auxiliary plate 6. The action of this form of the device is the sameas that shown in Fig. 2, the driving force being distributed in a moreefficient maimer than in the ordinary drive wheel for the reasonsstated.

In Fig. i I have shown the body portion 1 as provided with spokes 1while the auxiliary wheel 6 is also provided with spokes 6 The auxiliarywheel 6 has an integral extension 6 by means of which the pitman andconnecting rod are secured. The body portion 1 is provided with theusual lug 7 arranged to enter a recess in the auxiliary wheel, as shown.

In Fig. 5 I have shown a construction which is primarily designed forinternal combustion engines.- In this view the body portion 1 of thewheel is recessed to receive an auxiliary wheel 6. The latter has arecess arranged to receive an integral lug Both of the wheels 1 and 6are loosely mounted on the shaft 15. The latter has a drive member 16such as a gear or pulley which enters a recess in the wheel 6. The drivemember 16 is keyed to the shaft 15 and is provided with a pin 17 whichconnects it with the auxiliary wheel 6.

In this form of the device it will be observed that the drive shaft 15when rotating will carry around with the drive member 16 and also theauxiliary wheel 6. The power which is applied to the body portion 1however is transmitted through the lug 7 on the opposite side of theshaft in the same manner as described in connection with the enginedrive wheels.

The arrangement set forth above eliminates a great deal of theunsteadiness which is now occasioned by the ordinary driver having acounter-balancing weight on the opposite side from the connecting pin.In the older constructions, dead centering was frequent so that in orderto start forward, it was sometimes necessary to reverse to bring thewheels off dead center and then to proceed forwardly. In the presentconstruction this is not necessary since the force is so equalized thatwith a companion wheel connected with the pitmen :at there is never anydead center. The equalization of the force of the wheel results in again in power which is considerable.

In Fig. 7, I have shown a modified form in which the auxiliary wheel 6has a counter-balancing portion 21 consisting of a flange which overlapsthe body portion 1 in the manner shown in the drawing. This flange, itwill be noted from Fig. 8, is beveled outwardly. The flange forms acounterbalance for the pitman and driving pin, and furthermore it formsa cover for preventing the entrance of dirt or grit between theauxiliary wheel 6 and the main wheel. 1 The operation of this form ofthe device is substantially the same as that of the other formsheretofore disclosed.

When the connecting pin and the axle are in the horizontal line wherethe wheel would be ordinarily dead center, a movement of the pinupwardly gradually increases the thrust 116 of the pitman, and at thesame time the weight of the auxiliary wheel acts on the lug of the mainwheel, thus throwing the weight and gravity onto the main wheel andequalizing the steam pressure on the 120 connecting pin and throughoutthe wheel. hen the connecting pin passes downwardly below thehorizontal, it reverses the action of the opposite side of the wheel andhas the same action as described as far as the weight, 126 gravity, andaction of the steam pressure is concerned. Furthermore, this actionobviates dead pressure since with the lever action, the resistanceagainst the pin is overcome by the equalized pressure, thus renderingthe wheel more efficient than the ordinary wheel in which the pitman isconnected .gines, automobiles, airships, motor boats, all

stationary machinery, locomotive engines, electric cars, and also forr'ing bearings and any other machinery in which it is necessary tocounter-balance or to equalize the driving force.
